The Acts of Peter and Paul is a 4th century Christian text of the genre Acts of the Apostles. An alternate version exists, known as the Passion of Peter and Paul, with variances in the introductory part of the text.

The work appears to have been based on the Acts of Peter, with the addition of Paul's presence where before it was only Peter's.[citation needed] The work is dated to around 450 to 550. Latin as well as and Greek versions survive, with the latter usually being longer. The Latin versions sometimes end with "I, Marcellus, have written what I saw." This Marcellus is identified as a disciple of Simon Magus, who lived in the 1st century. Because of this obvious anachronism, since the text is clearly written centuries later, scholars have dubbed him Pseudo-Marcellus.[1]
